LIQUID-PUMP.

SPECIFICATION forming part of Letters Patent No. 763,367, dated June 28, 1904.

Application filed September 16, 1902. Serial No. 123,655. (No model.)

T0 (tZZ whom it may concern.-

Be it known that I, HoRA'rIo GoLLINs, a citizen of the United States of America, and a resident of Liverpool, in the county of Lancaster, England, have invented certain new and useful Improvements in or Connected with Liquid-Pumps, of which the following is a specification.

This invention has reference to pumps or pumping machinery for use in mine and other shafts or on the surface wheresuch pumps are at a considerable distance from the driving motive power; and it is particularly applicable for use in connection with and for operating plunger or ram or like pumps.

Some of the chief objects and effects, among others, of the present invention are to obviate and supersede the use of the expensive and heavy lines of pump-rods and the like which are commonly employed in mine-pumps and also to do away with the expense and labor of making balance-bobs or weights, which are necessarily employed in connection with pumps with heavy rods of the kind referred to and of excavating chambers for the same. At the same time it has for its object and effect to provide a simple mechanism or means for obtaining an increased volume of discharge and through asingle column or discharge-pipe with a given cost of machinery and work, besides other effects and advantages hereinafter specified.

The invention will be chiefly described with the aid of the accompanying drawings, which show one arrangement and construction of parts according to this invention; but, as is hereinafter stated, it is not restricted to the relative disposition orconstruction of the parts here shown and can be applied in different arrangements for carrying out pumping operations which may differ substantially from that herein illustrated without departing from its essential or controlling characteristics. Furthermore, this illustration shows one complete set of parts for delivering water between an intake or supply in a shaft and the surface; but by a repetition of the means or mechanism shown disposed below same a two-stage or miiltiplefstage pumping machinery will be provided, and the machinery or operating means illustrated is devised and shown to accomplish this, as hereinafter described.

Figure 1 is a front elevation of the machinery. Fig. 2 is a side elevation. Fig. 3 is a plan, and Fig. A is a section on the line X X of Fig. 2.

The chief characteristic of pumps or pumping machinery according to this invention is that a double or multiple set of pumpsare operated and the power is transmitted to them by adouble or multiple set of powertrans mitting means, which are connected together and arranged and adapted to operate in tension, the action of the tensional mechanisms being an alternating one corresponding with the alternation or reciprocating action of the pumps, and the part of one mechanism which is at the surface or upper end of the shaft or beginning of the system and is operated by the engine or motor is adapted to operate one pump by lifting the tensional gear connected with it and at the same time through other gear connecting the two mechanisms at the lower part or other end of the machinery to pull down or in the other pump, and then conversely when the engine-driven part at the shaft-head or beginning of the system connected with the plunger of the other pump-is moved by the engine it pulls up or in this pump and at the same time through the lower or outer connecting tensional gear it pulls down the other pump and its operating tensional gearing. Thus the two pumps receive an opposite or alternating direction of movement and action from the two engine-operated parts at the shaft-head or beginning of the system through the two alternating tensional operating mechanisms and the lower connecting mechanism. In connection with these tensional power-transmitting mechanismsby which the pumps are operated there are provided balancing mechanisms comprising wheels and belts, ropes, chains,'or equivalent means disposed at or near the upper part of each installation or stage of the mechanisms by which the two tensional mechanisms and the weights of the several parts connected with the two pumps are balanced by each other.

In the arrangement shown in the drawings the tensional pump-operating mechanisms are adapted and arranged to work two plungerpole pumps placed side by side at a station in a shaft by which each set of the said mechanisms operates one single-acting pump, (or a double-acting pump, if an additional inverted cylinder be added;) but instead of the pumps being placed side by side, as shown, they may be placed singly at certain distances apart, provided the same number of pumps be connected with each set of tensional operating gear or mechanism, so as to equalize the strain.

teferring now generally to the drawings, a and (4' represent tWo pairs of wheels mounted on two shafts a and reciprocated and worked to and fro a portion of a circle in opposite directions by the engine or motor at the shaftsurface, the power being applied to each pair by a pin (4 0 and 0 generally designate the two pumps, and p p the plungers of these two pumps, respectively, while n represents the rising main or discharge-column of the pumps.

In the position shown in the drawings the pin (6 of the pulleys a would be in the extreme forward position and the plunger 1) of the pump 0 and its operating mechanism in their extreme downward position, while the pin a" of the wheels (0 and the other plunger, 9, of pump 0 and the operating mechanisms would be in their extreme upward position. The parts are thus at one end of their respective strokes and in a position ready to be reversed. I

The tensional mechanisms connecting the sets of wheels a a and the pump-plungers p 2 comprise ropes, belts, chains, metal rods, or the like and connecting means and pulleys, and these will now be described. Connected with the wheels a at the point a are flat ropes or belts b, which lie on the peripheries of these wheels and extend down the shaft a certain distance, their lower ends being connected with a coupling-piece (Z through a cross-head c fixed thereon, the connection of the rope or belt ends with the cross-head being effected by threaded rods 11' and nuts, by which they can be adjusted to any required degree. The couplingpiece (Z has fixed to it at a lower point a cross-head c", to the ends of which are suspended the main descending wire ropes or metal rods (1, the connection being by adjustable threaded rods 00 and nuts, while at the lower ends of these metal ropes or rods e is another cross-head, 0", which is fixed to the plungei p, the connection of the ropes or rods 0 with the crosshead being by the screwed adjustable rods r0 Referring now to the operating means of the other pump, 0, the wheels a have connected with them flat ropes or belts 7/, similar to 7), and the lower ends of these ropes or belts are connected to a cross-head c by threaded adjustable rods :5 and nuts, and this crosshead 0 is connected to a short coupling-piece (Z, similar to (Z. On the lower end of this coupling-piece is a cross-head 0", similar to 0, and this cross-head carries the main descending ropes or rods 0, to which it is connected by the screwed adjustable rods in" and nuts, and the lower end of these suspension ropes or rods 0 are connected to a cross-head e fixed to the upper end of the pump pole or plunger p of the pump 0, by threaded rods r and nuts. The power and movement transmitted from one to the other of these sets of tensional connections connecting the operating-wheels M0 and their respective pump-rods p p is effected by a pair of fiat ropes or belts it, connected at their ends by threaded rods 00 and nuts to the cross-heads c 0 011 the pump plungers p and p, respectively, and passing under the lower pulleys These ropes or belts and pulleys transmit the upward motion or pull of the respective tensional gears alternately from the one to the other.

The two tensional operating mechanisms of the pumps 0 and 0 are connected together and balanced one from the other at the upper part by a pair of flat ropes or belts 9'. These belts are passed over and are supported by pulleys r, and their ends are connected to the two coupling-pieces d d by the cross-heads c 0 through threaded adjustable rods 8 and nuts. These balancing ropes or belts o and pulleys 9 are for the purpose of balancing the whole of the alternating series of ropes, belts, rods, chains or the like, cross-heads, and couplingpieces. For balancing the whole of the corresponding parts of the installation below this first or upper installation a pair of flat ropes or belts 1' and pulleys 9", over which they pass, are employed, the lower ends of such ropes or belts being connected to the pumpplungers p and p by cross-heads 0 and c thereon, the connection being by threaded rods t and nuts. The connection of this first installation of pumps shown with the second installation of pumps (not shown,) and which is below the first installation, and the transmission of power from the operating tensional gear or mechanism of these pumps to the second installation is effected by cross-heads c 0, fixed on the stems of the plungers p and p, respectively, and main descending ropes g g, connected to the ends of these cross-heads. It will now be seen that all ropes or rods, crossheads, connecting-pieces, and plungers connected to the pair of surface pulleys a are balanced by the corresponding appliances or parts connected to the other pair of surface pulleys, a, and it will be seen that the fiat ropes or bands It at the pump-station connect and transmit the power and motion from the one pole-plunger and its operating tensional mechanism to the other and cause the alternating action required.

In the arrangement and construction shown the rising main or discharge-column a of the pump serves as a support to the pulleys v" and 9' by means of divided cross-headsf, which are clamped onto the pipe or main a and the ends of which serve as axles for the wheels r Where this means of supporting the wheels 7- r is-undcsirable, they may be supported on fixed axles suitably supported in bearings'iixed in the shaft and be independent of this pipe. 7

In the arrangement and construction shown the pumps 0 0 are single-acting; but by employing another and an inverted cylinder in connection with each plunger and so arranging it that the upper end of the plungers work in the inverted cylinders each pump would be a double-acting one.

The various cross-heads, with their threaded connecting rodsand nuts connecting them a ready means of bringing and keeping the various parts taut and in their proper relative positions to each other.

The operation of the gear and machinery is as follows: Assuming the pump-plunger p to be at the bottom or extreme inner end of its stroke and the other plunger, 79', at the extreme upper and outer endof its stroke and with their operating parts at the same relative positions, as above described, when the wheels (a move inwardthat is, in their inward or upward strokethe pump-plunger 0 will be pulled up by the tensional connecting means, drawing water into the pump 0, and

in this action through the connecting ropes or belts I), the plunger p of the pump 0 will be pulled down, forcing the contents drawn into it on the previous upstroke into the deliverycolumn or rising main a. At the end of these strokes the movement and operation is alternated and the opposite functions are performed by the respective pumps, while at the same time the pumps in the second installation below will be similarly operated, the water delivered thereby being forced to the intake or tank for the upper station-pumps 0 0. (Shown in the drawings.) It will thus be seen that the continued alternating movements of the appliances will resultin continuous pumping operations and that through the weight of the connecting and power-transmitting means being small relatively with the solid or rigid lines of rods commonly employed in pumps and by means of the balancing arrangement the pumps admit of being operated at a much greater rate of speed, and consequently a corresponding increase of volume of water pumped can be effected.

Instead of placing the pumps proper in the shaft they can, if so desired, be placed in recesses or chambers cut into the side of the shaft or be placed in the tunnels and be operated by passing the working ropes or chains 0 0 over or under directing or guide pulleys or rollers at the points where the ropes may have to change their direction, and hence the In the drawings the means of operating the pump-actuating tensional mechanisms consists -of pairs of pulleys at the top of the shaft; but although such are convenient and advantageous, yet balanced levers or portions of pulleys and the like may be used instead of them.

'In use in most cases suitable catch-beams q would be placed across the shaft under the couplings or connecting-pieces d d of each set of mechanisms, sothat the mechanism or gear would be prevented from tumbling down the'shaft in' case of=breakage of the upper ropes or belts or mechanism. As further effects'and advantages under this invention by the balancing of the parts and by obviating the use of heavyrods and the necessity for excavating for balance-bobs or the like on the surface and in the mine a great saving in time, labor, and materials, and. consequently of expense, is accomplished, and also through it being rendered possible to work the pumps at a relatively high rate of speed a given volume of water can'be pumped at a diminished initial expenditure in machinery. A further advantage is that the mechanism and operating-gear of the pumps according to this invention are more durable than the wooden pump-rods as commonly employed, and consequently the expense of repairs is reduced and a greater exemption from accidents is secured. Then, again, by the tensional system of pump-actuating mechanism described the pump portions proper of the plant can be placed in chambers in the side of the shaft and entirely out of the shaft proper, thereby leaving more room for the circulation of airand giving greater space generally in the shaft.

Having now described my invention,whatI claim as new, and desire to secure by Letters Patent, is
